An AL-1530 Magnetic Loop Antenna delivers the HF signal via a distribution amplifier to the receivers. Additionally a LFL-1010 Magnetic Loop Antenna with enhanced LW sensitivity is connected to the ICOM R-9500 receiver for reception of VLF signals.
Both antennas are rotatable and may - together with a PA0RDT MiniWhip - via a little patchfield be connected to different receivers. The performance of the antennas is ok, the MiniWhip delivers excellent signals in the MF/LF range.
Flipping a few switches for receiver audio muting is faster than turning down 4 volume controls - that's the little box on the desk next to the digital 2-channels recorder from TACAMO.

I'm not a HF decoding specialist, HOKA's CODE300 software is a valuable help. Other little programs are useful: Music Editor Free, PCHFDL and DX Atlas.
For an analysis of unknown digital modes "SA" Signal Analyser is the real thing: It offers outstanding accuracy and speed combined with superior graphics. It is not expensive and MSM, the people behind "SA", are very helpful. For more see my: Links

Thanks to an extensive earthing system reception quality is not bad, surprisingly my wife's new washing machine with frequency controlled motor is my main concern and I had to displace antennas a few times for acceptable results. PLT is another subject, it seems, you just can't avoid that crap - luckely enough the source is rather distant.

The Radio Direction Finder TD-C358 gives the best results, which such a simple system can provide; I could eliminate nearly all systematic errors, but steep angle reception in the evenings will remain a problem. Look here for more: Radio Direction Finding .

Strong stations which only show up sporadically are best recorded by means of a Voice Activated Switch. For this unit I used a circuit diagram found once elsewhere. It uses the Line output of the receiver. The switch selects input 1 or 2, the controls adjust the signal amplitude and the duration (hysteresis) of the registration period.
Note: If the s/n ratio is bad, the unit will not work properly. Automatic Gain Control increases the noise - try to switch it off.

The ready unit - a great help for all those who need some sleep.
Circuit diagram part 1. The bandpass limits the sensitive audio range, Morse specialists may easely narrow it even more (change RC values).
